IMDB Replication - Sybase

Multiple primary IMDBs/RDDBs with a shared template
In the previous section, the situation described was that of a single primary IMDB/RDDB with its own
template database.
However, it may well be desired to have multiple identical primary IMDBs/RDDBs with identical schemas
in an ASE server, for example in scale-out scenarios where an incoming workload is spread over multiple
IMDB databases. While it is certainly possible to create a separate template database for each such
primary IMDB/RDDB, it may be more convenient to use a single template database for multiple
identical primary IMDBs/RDDBs.

Multiple replicated primary IMDBs with a single template database
For setting up multiple identical primary IMDBs/RDDBs with the same template database, follow the
setup steps below (see page 21 for a full code example). Note that this requires that all IMDBs/RDDBs
connect to the same Replication Server.
1. First create the template database and the first primary IMDB/RDDB as described on page 6.
For each additional IMDB/RDDB that must also be a replicated primary database based on the existing
template database, follow these steps:
